Macaulay Culkin and Seth Rogen, among other celebrities, have expressed their sorrow over the passing of Catherine O’Hara, who died on Friday at the age of 71. This loss has left a significant impact on Hollywood, as O’Hara was widely cherished both on and off the screen.

The beloved actress passed away in her Los Angeles home after a brief illness, as confirmed by the Daily Mail. While the cause of her death remains undisclosed, her legacy continues to resonate deeply with fans and colleagues alike.

O’Hara was celebrated for her versatile acting skills, notably portraying the mother of Culkin’s character in the iconic Home Alone movies. She reached new heights of popularity with her role as Moira Rose in the critically acclaimed series Schitt’s Creek, earning an Emmy in 2020 for her brilliant performance.

Her filmography spans a range of beloved classics, including Beetlejuice, The Nightmare Before Christmas, Best in Show, and A Mighty Wind. Most recently, she captivated audiences in her role as Patty Leigh in Apple TV+’s The Studio.

Throughout her illustrious career, O’Hara shared the screen with numerous Hollywood stars, many of whom have taken to social media to honor her memory and celebrate her remarkable contributions to the entertainment industry.

The legendary actress starred alongside countless Hollywood’s A-listers, many of whom took to social media to pay tribute to the star in the wake of her death.

‘Mama. I thought we had time,’ Culkin wrote, alongside two pictures – one of the pair in Home Alone and another more recent image after the duo reunited on the Hollywood Walk of Fame.

‘I wanted more. I wanted to sit in a chair next to you. I heard you but I had so much more to say. I love you,’ he concluded the post. ‘I’ll see you later.’

Seth Rogen said he was devastated by the news of O’Hara’s passing. 

The actor and comedian, who worked with O’Hara in his award-winning Apple TV series The Studio, posted a sweet photo of the late actress with a mischievous smile on her face as she poked him on the back. 

‘Really don’t know what to say…’ Rogen started his post. ‘I told O’Hara when I first met her I thought she was the funniest person I’d ever had the pleasure of watching on screen. 

‘Home Alone was the movie that made me want to make movies. Getting to work with her was a true honour. 

‘She was hysterical, kind, intuitive, generous… she made me want to make our show good enough to be worthy of her presence in it. 

‘This is just devastating. We’re all lucky we got to live in a world with her in it.’ 

Ike Barinholtz, who also starred alongside O’Hara in The Studio, expressed his sorrow in a statement shared on Instagram.

Alongside a photo of the two of them standing together on a staircase, he penned: ‘I never in a million years thought I would get to work with Catherine O’Hara let alone become friends with her.

‘So profoundly sad she’s somewhere else now. So incredibly grateful I got to spend the time I did with her. Thank you Catherine, I love you.’

O’Hara’s Schitt’s Creek co-stars, Dan Levy and his father Eugene Levy, also shared touching tributes to the actress.

Dan, 42, expressed that O’Hara — who starred as his eccentric mother Moira Rose on the show — was ‘family’ both on and off the screen, after news broke that she passed away at age 71.

‘What a gift to have gotten to dance in the warm glow of Catherine O’Hara’s brilliance for all those years,’ Dan wrote in an Instagram tribute, where he also shared two photos of them.

‘Having spent over fifty years collaborating with my Dad, Catherine was extended family before she ever played my family. It’s hard to imagine a world without her in it.’

‘I will cherish every funny memory I was fortunate enough to make with her,’ he added. Dan wrapped up his tribute sharing that he was thinking of her loved ones: ‘My heart goes out to Bo, Matthew, Luke and every member of her big, beautiful family.’

Meanwhile Eugene, 79 — who starred on Schitt’s Creek as Moira’s husband, Johnny Rose, and was a longtime friend and collaborator of O’Hara’s — told Daily Mail in a statement: ‘Words seem inadequate to express the loss I feel today.’

‘I had the honor of knowing and working with the great Catherine O’Hara for over fifty years. From our beginnings on the Second City stage, to SCTV, to the movies we did with Chris Guest, to our six glorious years on Schitt’s Creek, I cherished our working relationship, but most of all our friendship. And I will miss her.’

He added: ‘My heart goes out to Bo, Matthew, Luke, and the entire O’Hara family.’

Michael Keaton, who co-starred alongside O’Hara in 1988 classic Beetlejuice, as well as its 2024 sequel, shared a picture of the two of them with a touching caption.
